Specification of Letters Patent.

Application filed August 17, 1908. Serial No. 448,837

The 0 j ect of the invention is to provide aphonograph stopping devicethat will automatically stop the operating mechanism when the end ofeach record has been reached.

This and other objects I attain by the novel construction andarrangement of parts illustrated in the accompanying drawing, in which:

Figure 1 is a top view of thewell known cylinder record type ofphonographwith my stopping attachment applied thereto. Fig. '2 is afront elevation of Fig. 1. Fig; 3 is a rear elevation of Fig. 1. Fig. 4is a detail view of the stop-collar which forms one of the main workingparts of the'device.

, Referring to the drawing by reference numerals, 1 and 2 designate resectively 'the' base and frame of a phonograp which .are often cast inone piece, the frame being offset upwardly about at the middle as bestshown in Figs. 2and -3.

'The main shaft 3 is journaled in the bearin s 4 and 5 and carries thecylindrical record ho der 6, the screw threaded bar on screw 7 and thepulley 8 driven by belt 9, whichisconnected to the motive power (notshown) underneath the base plate.

Near .the rear edge of. the frame another shaft 10 extends theentire-len' th of the machine parallel to shaft 3 and is fastened ateach end to lugs 11 by means of screws 12.

On the shaft 10 slides a sleeve 13 having 3 secured to one end thereproducer-carrying arm 14 and the reproducer 15 with tube 16 to, whlcha horn (not shownlmay be attached.

Said arm has an extension 17 in front of the from it and having athreaded member 21 engaging the threads of the screw 7.

All of the above. mechanism is common in the phonographs now used andsaid parts also constitute the mechanism that is used in .ward the leftof the machine and connection with my stopping device, which I will nowbe described.

Near the olfset of the frame I provide in the front and rear of thephonograph, bearings 22, in which is journaled a horizontally disposedrock shaft 23 having at its front end a horizontal rocker arm 23projecting tothe front of it (as bestshown in l igs. 1 and 2). normallyvertical. arm 24 (see Fig. 3) to which is secured by rivets 25,a toothedsector 26 engaged by a catch 27 operated by a finger lever 27 5fulcrumed at 28 to a hand lever 28, which is fulcruI-ned at 29 to thedepending radial ar'm 29 of the sector.

The lever 2.8 has pivoted to it at 30 one end of a horizontalcontrolling rod 31, extending to the left (in Fig. 3) and'ha'ving itsother end bent at an an le and formed into a collar 32 looselyencircling the shaft 10 to slide thereon. In Fig. 3 it is clearly shownthat-the collar 32 islocated at a point 0 osite to the end of the waxcylinder 33 s own in dotted lines). Should the cylinder be shorter orlonger or the ieces to be reproduced are of different lengt s as can beseen by looking at the sound producing spiral grooves in the cylinder,the collar 32 is broughtto a point 0 posite the end of the cylinder orpiece by arallel to The rear-end of said shaft 23 has a short p acingthe lever 28 with its'catch 27 in a its extremity provided with 'avertical groove or notch 34, adapted to engage the common hand-oeratedstopping lever 35., which is ivote underneath the base. -Saidstopping ever whenpushed to the left sets the motive powerin operation(by means not; shown)- and'the belt or or the pulley 9 turns the shaft 3and thereby the screw 7 and the cylinder 6.

The screw threads being engaged with the member 21, cause the sleeve 13and its parts, including the reproducer16 etc;, to move toward the right(1n Figs. 1 and 2) until the end 36 of the sleeve 13 takes against thecollar 32.

-By the time this takes place the music piece has come to an on but thesleeve'contmues to move thereby p lling on rod 31, which in lever 35,allowing a spring 37, connectedwith. the lever 35 and any suitableplace'near the front bearing, to pull the lever 35 tothe po- I place atthe end of either long or short rec- I claim' is:

verse osition to the line of movement of the sition 35 (see Fig. 2)thereby stopping the motor; and by means of the lever 28, rod 31, collar32 and sector 26 the stopping takesords, as already above explained.Swinging on a pivot 39 in the frame is a bearing 38 normally supportingthe end of the shaft 3.

Having thusdescribed my invention, what 1. In a phonograph and mountedon they frame thereof, a rock shaft arranged in transstarting lever ofthe machine in operative position, and a spring arranged to pull thestarting lever lnto idle position when the horizontal arm is disengagedtherefrom. v

2., In a phonograph and mounted, on the I frame thereof, a rock shaftarranged in transverse osition to the line of movement of the reproucer-,a vertically disposed rocker arm on the rock shaft, an operatingrod pivotally connected therewith and having a guided portion adapted tobe engaged by the member of the machine carrying the reproducer, also ahorizontally disposed rocker arm on saidshaft and adapted to normallyhold the starting lever of the machine in operative position, and aspring arranged 'to ull the starting lever into idle position w .1en thehorizontal arm is disengaged therefrom, and adjusting means in theconnection between the vertical rocker arm and the operating rod, forthe variation in the lengths of records played. 1

In testimony whereof I in presence of two witnesses.
